BURNER FOR I'NCANDESCENT GAS-LIGHTING.

SPECIFICATION forming part of Letters Patent No. 530,775, dated December 11,1894.

' Application filed a... 22.1294. Serial No- 515,s4s. (No an.)

To all whom i t may concern,-

Be it known that}, Monrrz HoRWITz, a subject of the Emperor of .Germany,residing at Berlin, Germany, have invented certain new and useful Improvementsin Burnersfor Incandescent Gas-Lighting, of which the fol-- i lowing is a specification.

My invention has relation to that class ofgas lamps in which the full illuminating ef-. feet is produced by the incandescence of a mantle, hood or body suspended about or above the burner; and in such connection it relates more particularly to the construction and arrangement of such a burner for said purpose. 7 p

The principal objects of my invention are first, to provide a burner arranged somewhat on the plan or type of a Bunsen burner for lighting purposes by employing an incandescent mantle or body suspended therefrom in a certain manner; second, t0 provide aburner arranged in such manner as that without the aid of mechanical'devices or appliances-the flame is made to spread or difiuse the light so that every part of the incandescent mantle or body is brought into contact with the flame, whereby said mantle or body is thor-, oughly utilized and a maximum illumination is derived therefrom; and third, toprovide a burner in which the spread or diffusion of the flame is effected by means of'a strong current of air conveyed through the center of the flame, whereby the air spreads the flame outwardly into tubular form andv causes. the same to contact with a truncated incandes cent mantle or body so that every part of the latter is made to glow.

My invention consists of an incandescent gas lighting burner constructed, arrangedand zontal section of a disk provided with a dou- *blerow of perforations of the burner of Fig. g3, and Fig. 5, is a top or plan view of a. perforated plate-of theburner taken on theline jA-B, of Fig. 3.

Referring to. the drawings with reference itoFig. 1,.the burner consists of a casing a, ltowhich is secur ed,a conical throat b. c, is jthe gas inlet conduit, tube or duet formed ,preferably integral with or secured to the ,throat I), and provided with a' series of oblong {openings 0, through which openings air is led or drawn to permit ofan admixture-of the j air and gas in theinlet conduit or tube 0. In the casing a, atube or shell 01, is provided pref- ,erably in conical form, and having branches e, extending through openings provided in the conical throat b, to permit of the flow of jpure air therethrough into the body of the tube or shell d. The object of such flow of Ythe current of air into said internal shell d, i is to effect a tubular like spreading or diffusmg of the flame of the burner. The upper.

end of the tube or shell d, as illustrated in Fig. 1, is bent over to form a flangef, and the ,space between this flange and the casing a, lforms an outlet for the gas held as it were gby reason of said flange insuspension and in such manner as to avoid any unpleasant roar- }ing of the flame. The current of air while ithe gas is burning, passes in the direction of Ethe arrow in Fig. 1, out of the upper end of fthe shell d,and impinging against the flame, which consequently difiuses the same somewhat in tubular form and the incandescent body or mantle w, is thus acted upon by the flame at every point or portion thereof. This incandescent mantle 0c, of the form of a truncated cone, as fully illustrated in Fig. 2, is,

means of a perforated disk 1', connected with a pin or stem.g, and which stem or pin at the lower end is provided with a perforated disk h, through which perforations the pure air passes vertically into the internal space around or about the body of the mantle w. The disk h, is preferably arranged so as to engage in the mouth in the upper portion of the conical shell or casing d, asillustrated in In the burner illustrated in Fig. 2, the mix- ICO ture of gas and air is conveyed through an annulus or ring 0 from the perforated inlet nozzle 0 into the chamber formed by the walls of the tubes or shells a, and d, and the air enters through the open lower end of the inner tube d, as indicated by the arrow in Fig. 2, and is forced or drawn against the inner surface of the flame. The space between the flange f, of the tube at, and the casing a, forms a passage-way for the escape of the combustible mixture composed of air and gas. The perforated bottom plate f, of the flange f, serves to support [a corresponding perforated plate h', connected with the lower endof the pin or stem g, and carrying at its upper end a perforated disk '5, preferably made of asbestos,mica or other suitable material, with which the incandescent mantle or body an, is engaged, to support the same to position within the chimney or globe z. The length of the stem and the diameter of the casing a, are such as that the lower end of the incandescent body or mantle so, suspended from the disk 2', snugly engages or contacts with the exterior surface of the casing a. By this arrangement the flame is forced outward by the inner current of pure air, assuming the form of the incandescent body or mantle 00, so that the latter is brought to a glow at every portion thereof. By turning the perforated disk h, on its corresponding side or disk f, in such manner as that the openings are more or less covered, the current of air can be readily regulated through the chamber or tube d; as clearly illustrated in Fig. 2.

In Fig. 3, a still further modification of my invention is shown, and in which the combustible mixture of air and gas is conveyed through a divided or bifurcated pipe or conduit 0 from the perforated inlet nozzle or nipple 0 7a, is a plate engaging the upper end of the forked or branch pipe or conduit 0 and having openings m and m, communicating with the branches of the conduit 0 and a central opening n, leading to the central funnel shaped tube d The air is adapted to cause the flame to spread or diffuse through the pipe (1 in the direction of the arrow in Fig. 3. The casing a is suitably secured to the top edge of the disk or plate 70. Z, is a collar or open tapering hood engaging with said plate and extending upward concentrically or substantially so to the central conical tube (1 The object of this hood or collar Z, is to confine to some extent the mixtureof air and gas and thus secure the most thorough commingling of both constituents of the inflaming or gaseous mixture for insuring the best results in the burning thereof for illuminating purposes. The chamber between the casing a and the chamber (1 is closed at its upper end by means of a disk 0. This disk is made of lardite or other suitable material and is provided with two series of openings 0, which taper toward their lower ends so as to form a circular opening .0 underneath the disk 0. By means of this arrangement and the conical form of the tube d the combustible mixture is forced through the openings 0, under considerable pressure. The plate h of the stem g, is secured to the upper end of the tube C1 and is preferably provided with slantingopenings and at its lower extremity with a conical projection h for directing the pure air in its passage through the tube d against the inner side or surface of the flame. An annular spring clamp or other suitable device for engaging the globe or shade 2, at the lower end is secured to the casing of the lamp, in any well understood manner for holding the same to required position.

Having thus described the. nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An incandescent gas burner, comprising a casing provided with a tapering bottom with a perforated nipple or nozzle, an internal ta.-

pering tube provided with branches for the introduction of air therethrough and with a flanged top arranged close to said casing so as to form a narrow passage between said tube and shell to permit of a thorough admixture of the air and gas, a stem provided with top and bottom disks, a'mantle supported within a globe or shade from one of said disks and engaging said casing, substantially as and for the purposes set forth.
